You must have a appropriate financial product for your primary residence.
Possessing an expensive or inaccurate financial product is wasteful and can cost you thousands of dollars in unnecessary fees and interest each year as your residential property, owner occupier, or principal place of residence does not qualify for ordinary tax benefits.
Your retirement may also be impacted, so we advise you to have your house loan reviewed by a specialist and to consider refinancing your mortgage at least once every 24 to 36 months to ensure that your terms are still competitive.
